Well, my first audio device was a transistor radio purchased in 1960. I was 11 years old. My father co-signed for a loan at the JC Penneys store.
Had to use my parents console stereo throughout Jr high and high school.
First real system was purchased on Okinawa 1970, Pioneer 63DX speakers, Sansui AU555 Integrated, Dual 1219 TT with Shure V15 type II cartridge, Teac RtoR deck. Owned that system till 1982. Wasn't in possession of it over many of those years as I spent much time traveling trying to find myself.
